SYNOPSIS

#include <multheap.h>
int hppop(void);

DESCRIPTION

hppop removes the heap specified by the previous call to hppush from the heap stack, restoring the previous default heap. If no heaps are on the heap stack, a warning will be produced.

RETURN VALUE

hppop returns 0 if the prior heap is restored and -1 if there are no currently pushed heaps.

IMPLEMENTATION

Each coprocess (including the implicit coprocess that represents the main program) has its own heap stack, which is maintained independently.

EXAMPLE

See the example for hpextract.
